REVOLVING SCRUBBING-NIACHINE.

SPECIFICATION 4forning part of Letters Patent N0- 773,4.36, dated. October 25, 1904.

Application filed August 9, 1904. Serial No. 220,067. (No model.)

To all whom, it may concern:

Be it known that I, W ILLIAM JOHN TANGEP.- Y

MAN, a citizen of the United' States, and a resident of Hammond, in the county of Lake and State of Indiana, have invented a new and Improved Revolving Scrubbing-Machine, of which the following is a full, clear, and exact description.

The invention relates to brushing and scrubbing; and its object is to provide a new and improved revolving scrubbing-machine which is simple and durable in construction, very effective in operation, and arranged to permit the operator to conveniently move a brush about, at the same time rotating' it and exerting any desired pressure to insure a thorough scrubbing of the surface under treatment.

The invention consists of novel -featuresand parts and combinations of the same, as will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings,

forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a side elevation of 'the improvement. Fig. 2 is a front elevation of the same, and Fig. 3 is an enlarged sectional side elevation of the lower or brush end of the machine.

The padded breastplate A of the machine is provided with suitable straps B for fastening the breastplafte to the body of the operator. The breastplate A is pivotally' connected with the upper end of a frame O, in which is journaled the transversely-extending shaft D, having each end flattened or made polygonal to permit of conveniently applying a crank-arm E to either end of the shaft, thus allowing the operator to turn the shaft D with his hand. A thumb-screw E serves to fasten the crank-arm E ,in position on the corresponding end of the shaft D.

On the shaft D is secured a bevel gear-wheel F in mesh with a pinion F, secured on a shaft G, extending through and journaled in a tube O, forming a part of the main frame O. On the lower end of the tube O is secured the fork H of a universal joint H, having a ring pivoted in the fork H and pivotally connected with a fork H3, having its hub H4 forming a bearing for a pin or shaft I, attached to the back of the brush J. The upper end of the pin J is connected by a universal joint K with the shaft Gr to rotate the brush on rotating the s'aid shaft Gr. The universal joint K is provided with the upper fork K', screwed or otherwise secured on the lower end of the shaft G, and in this fork K' is pivoted the block K2, pivotally connected with a fork K3, screwed or otherwise secured to the pin I vof the brush J. From the foregoing it will be seen that the universal joint K is surrounded by the universal joint H, which latter forms a bearing for the pin or shaft I of the brush J. The latter is preferably made cylindrical in shape and provided on the peripheral face of its back with a cushion J' in the shape of a rubber ring to prevent marring furniture, base-boards, or other articles in the room and with which the brush is liable to come in contact. v

On the frame O and preferably below the pinion F is arranged a pivoted handle L, adapted to be taken hold of by the operator 'with one hand for conveniently directing the frame about, so as to bring the revoluble brush J to the desired portion of the surface to be cleaned.

The operation is as follows: The breastplate A is fastened to the body of the operator and then the latter takes hold with one hand of the crank-arm E and with the other hand of the handle L andY then turns the crank-arm E, so that the shaft Disrotated, and the rotary Vmotion is transmitted by the bevel gear-wheel F and pinion F to the shaft Gr, which by the universal joint K rotates the brush J. By the operator having the breastplate A attached to his body he is enabled to exert any desired downward pressure on the frame O, and by the universal joint H on the brush 'J to press the bristles thereof with more or less force into contact with the surface to be cleaned, and by the use of the universal joint H the brush J is held at all times level and in proper contact with the floor. By the operator having hold of the handle L the frame O can be readily swung about so as to bring the brush J into the desired posi- IOO tion-that is, over the portion of the surface to be cleaned.

The scrul bingmachine described is very simple and durable in construction, can be easily manipulated, and moved to the desired place to be scrubbed and cleaned.

H avingth us described my invention, I claim as new and desire to secure by Letters Patentl. A revoluble scrubbing-machinc, comprising a frame for attachment to the body of the operator, a manually-controlled gearing on the said frame, a scrubbing-brush, and a universal joint connecting` the gearing with the said brush.

2. A revoluble sci-ubbiiig-machine,comprising a frame for attachment to the body of the operator, a manually-controlled gearing on the said frame, a scrubbing-brush, a' universal joint connecting' the gearing with the said brush, and a handle on the frame. to allow of moving the machine about.

3. A revoluble scrubbing-machine,comprising a frame for attachment to the body of the operator, a manually-controlled gearing on the said frame, a scrubbing-brush, a universal joint connecting the gearing with the said brush, and a second universal joint on the frame and in which the brush is journaled.

4. A revoluble scrubbing-machin e, comprising a frame for attachment to the body of the operator, a manually-controlled gearing on the said frame, a scrubbing-brush, a universal joint connecting the gearing with the said brush, a handle on the frame to allow of movingI the machine about, and a universal joint on the frame and in which the scrubbingbrush is journaled.

ff/sass 5. A .revoluble scrubbing-machine, com prising a frame provided with a breast-plate having straps for attachment to the body of the operator, a shaft journaled in the said frame and provided with a crank-arm, a bevel gearwheel secured on the said shaft, a second shaft journaled in the said frame and standing at an angle to the said crank-arm shaft, a bevel-pinion secured on the said second shaft and in mesh with the said bevel gear-wheel, a universal joint having one member attached to the said second shaft, and a revoluble brush connected with another member of the said universal joint.

6. Arevolublescrubbing-machine,comprising a frame provided with a breastplate having straps for attachment to the body of the operator, a shaft journaled in the said frame and provided with a crank-arm, a bevel gearwheel secured on the said shaft, a second shaft journaled in the said frame and standing at an angle to the said crank-arm shaft, a bevel-pinion secured on the said second shaft and in mesh with the said bevel gear-wheel, a universal joint having one member attached to the said second shaft, a revoluble brush connected with another member of the said universal joint, and a handle pivoted on the said frame.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
